Letters Patent No. 84,021, dated November 10, 1868.

IMPROVED GAS-MACHINE.

The Schedule referred to L1; these Letters Patent and making part: of the lame.

To all it may concern:

Be it known that I, WILLIAM THOMPSON, of Cleveland, State of Ohio, have invented a new and improved Gas-Machine; and I do hereby declare the following to be a full and exact description of the same, reference being had to the annexed drawings, forming part hereof, in which Figure 1 is a perspective view of my machine.

Figure 2, a vertical section of the same.

Figure 3, a View of the top of the lower carburettingcylinder.

Figure 4, an internal view of the upper oarburettingcylinder.

Figure 5, an internal view of the lower carburettingcylinder. Figure 6, a detached View, showing the pipe for conveying the partly-carburetted air from the lower to the upper carburetting-cylinder.

. Figure 7, a detached vertical section of upper cylinder, showing the pipe for admission of partly-carburetted air.

Figure 8, a detached View of the crauk-bellows and airrbag.

My invention consists in a portable gas-machine, by means of which burning-gas can be produced cheaper than by the old method, and by its use any private family situated in-thc country, far from any town, can burn gas independent of street-pipes or connections.

Besides, in my machine, all liability to explosion is obviated.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.

Sponge, F, or any other suitable substance, should be placed in the upper and lower. carburetting-cylinders, I and E,'as shown in figs. 4, 5, and 7, and should be thoroughly saturated with gasoline or any light-oil or gas-producing fluid. It is advisable to place finer oil in the upper cylinder than in the lower.

In the drawings, a a are bent arms or elbows, as shown, which may be turned by a crank or weight, by hand or other convenient power, thus operating the bellows B B, of which there may be two or more, in order tocreate a steady and even flow of air. These bellows, through apertiu'es B B, force air up into the receiving-bag O, the ball L and cord K preventing the admission of too much air, as, when the bag O is filling, its top rises, gradually tightening the string K, until the ball L in pipe D rises to the mouth of the pipe, and prevents the further rising of the top of bag 0; thus preventing the bag distending further, and stopping the admission of air.

The top of the pipe is so formed, with open-work or cross-bars, that the ball does not shut off the passage of air through 'pipe D to the lower c'arburetting-cylinder- M sustains a weight, which, pressing on the top of the bag, as shown in fig. 2, forces the air down through pipe D, into and through the perforated coil-pipe D, figs. 5 and 2. It then enters the saturated sponge F, thence through said sponge, following the course of the continuous-coiled partition G, being partially carburetted' in its passage through the saturated sponge. Escaping at the outside end of the partition, it enters the pipe H, and is forced up into the upper cylinder, I, which it enters at H, fig. 4. Driven through the saturated sponge F, between the partitions J, following a winding course, as indicated by the arrows, it is thoroughly and completely carburetted, and emerges into the chamber S, which chamber is filled. with lime or any other purifying-substance, through which the air, which has now become gas, passes, being purified in its passage, and issues finally at the point B, fit for burning.

A cock and pipe, T, carry oii' any surplus oil from the upper to the lower cylinder, and any surplus in the lower cylinder is carried off by thecock -l".

Havingthus described my improvement,

What I claim, and desire to secure by Letters Patent, is-

1. The bellows B B, for forcing air into the receivingbag, as described, in combination with the carburetters and purifiers.

2. The combination of receiving-bag O and bellows B B, substantially as set forth, with the upper and lower carburetters.

3. The arrangement of the bellows B B, the large air-bag O, the passage-pipe D, and the perforated coilpipe D, substantially as set forth.

4. The coil-partitions G G G, filled with sponge or other equivalent material, forming a lower carburet tin g-chamber, substantially as set forth, in combination with the purifier.

5. The combination of the purifying-chamber S and the upper carburetting-chamber, substantially as described.

6. The pipe T and cook T, for conveying residue or surplus oil from the carburettiug-cylinders, substantially as described. I

7. The combination of the bellows B B, the receiving-bag G, the passage-pipe D, the coil-partitions G G G, the chamber S, the pipe T, and cook T, when the said parts are arranged, combined, and operating as and for the purpose herein set forth.
